it looks like a rallysport. clean your carb and your tank. fresh gas and all that. then clean the points. a pipe is a great place to start on these bikes. expansion exhausts for garellis ar almost always hack and weld though, so you'll have to find a pipe that you like and have it welded onto the stock header. nothing hard. you can get polini NOI 70 kits for around 175 and a PHBG carb for around 100. basically for about 400 bucks you can have an impressively fast bike.
so yeah. in this order
pipe
carb
kit.
done. enjoy it, my garellis make me happy everyday.
